New York Times: “A 2022 study by a pair of University of Montana scholars found that Mr. Trump’s speech complexity was significantly lower than that of the average president over American history…”
“The Times analysis found that Mr. Trump speaks at a fourth-grade level, lower than rivals like Gov. Ron DeSantis of Florida, who speaks at an eighth-grade level, which is roughly average for modern presidents.”

Any intelligent, insightful person of any political persuasion who has heard Trump speak or read his tweets with numerous mispellings and grammatical errors knows what a lamebrain he is. Any intelligent, insightful person of any political persuasion who is aware of Trump's many bankruptcies and unpaid vendors would not believe he is a shrewd businessman.
